Definitions

  • the present invention relates to an image processing apparatus for storing and reading out image data.
  • the identification (ID) card of the user is inserted into the ID card reader 205 and the user's ID code Memorized on the card is read out and stored on the memory of the control circuit 206.
  • the original image placed on the orign1 stand is optically read in by CCD 201 and turned into electric signals.
  • the output from CCD is amplified by an analog signal processor 202 and then digitized by a digital signal processor 203, followed by signal processing including shading correction.
  • a control circuit 206 regulates the flow of image data, and the read-in image data are stored in an inage storage 207. These stored image data are printed on paper by a printer 204. Thus the copying ends.
  • Another ID card is inserted into the ID card reader. If the ID code of the second user is different from that stored on the memory of the aforesaid control circuit 206, the image data in the foregoing image storage 207 will be erased. If, on the other hand, the ID code is identical with that of the first user, the recopying lamp will go on, indicating to the user that the foregoing image data stored in the foregoing image storage 207 can be printed again. If the user chooses to recopy, the printer 204 will output the image data stored in the aforementioned image storage 207.
  • This image copying apparatus can secure the confidentiality of image data, because it erases the image data stored in the above-mentioned image storage 207 if the ID code of the new user is not identical with that of the previous user. However, since the image data stored in the inage storage 207 is erased when another person with a different ID code uses the machine as described, the first user with the identical ID code can not pick out the image data in the image storage again. The inage data is already lost.
  • the present invention is disclosed for the purpose of providing an image processing apparatus which can secure the confidentiality of stored image data without making the operation complicated.
  • the present invention adopts the means described below on an image processing apparatus for storing the inputted image data in an image storage means 108 and outputting the image data newly inputted or stored in the aforesaid image storage means 108 by image outputting means 110. That is to say, the above-mentioned image processing apparatus forms the basis of the present invention.
  • the image processing apparatus controlls the user corresponding to the authorization code and the user's ID by a user control means 104.
  • the user directs an authorization code inputting means 102 to read the authorization code recorded on an authorization medium.
  • the users then directs a user ID inputting means to input the user's ID information whichi inlcudes the user authorization number of its own issued when the user was registered.
  • the user controlling means 104 specifies the user based on above authorization code inputted by the authorization code inputting means 102 and the user ID information inputted by the user ID inputting means.
  • the function-limiting means 106 limits the functions avaliable to the user.
  • the above function-limiting means 106 is designed to limit such functions as a function to store the image data in an image storage means 108 and a function to read out the image data stored in the image storage means 108 and to output such data from above image outputting means 110.
  • This arrangement can identify the user if the user authorization number is inputted by the user ID inputting means even when the authorization medium is not available at hand. Also, if the user is not registered, the use of the image processing apparatus can be limited. This way, the filing of image data by an unidentified person can be blocked and the confidentiality of the stored image data can be secured.
  • the user control means 104 controls group identification information which indicates the user's group, in addition to the user corresponding to the authorization code and user ID information.
  • the image data control means 105 controls the user who registered each image data as well as the access information that limits the access to each image data by respective user.
  • the user control means 104 extracts group identification information as well as specifies the user based on above authorization code inputted from the authorization code inputting means 102 and the user ID information inputted from the user ID inputting means. Further the image data control means 105 extracts the user who registered the image data and the access right to that particular image data. And then a function-limiting means 106 limits readout of above image data from image storage means based on the information on the user, group identification and access right specified or extracted in this way.
  • the access right information controlled by the image data control means 105 in relation to the image data is composed of group identification information corresponding to the user who registers the image data, specified by the user control means 104.
  • the access right can also be set as necessary by the user who registers the image data.

  • the authorization code inputting means 102 reads out the authorization code recorded on the authorization medium and notifies the user control means 104. If the user authorization number is inputted on the operator control panel 101a instead, the user authorization number is held in a panel control 101b of the operating means 101, which will notify the user control means 104 of the user authorization number if the execute button on the operator control panel 101a is pressed.
  • the user control means 104 which controls the users by a user control table 10 described in the following, decides by consulting the user control table 10 whether the authorization code or the user authorization number of the user is registered when notified of the authorization code from the authorization code inputting means 102 or notified of the user authorization number from the operating means 101, and notifies the function-limiting means 106 of the decision (Step 102).
  • the user control table 10 contains such information as the authorization codes 11 recorded on the authorization medium as, for example, shown in Fig. 3, the distinctive user authorization numbers 12 issued at the time of the user being registered, the users' names 13 as full names or nicknames by which the user can be identified and the registration date 14 which indicates the date when the user is registered by the image storage means 108 as hard disk, for example. It is noted that for the authorization code 11, a code of many figures would cause no inconveniences because it is recorded on the authorization medium, but the user authorization number 12 should be a small one as the user inputs it on the operator control panel 101a by finger.
  • the function-limiting means 106 issues an operation permit, notifying the image data control means 105 and the panel control 101b. Notified of the operation permit, the panel control 101b notifies the user that the apparatus is now ready for use as by changing LED in the execute button from red to green (Step S 103).
  • the function-limiting means 106 does not issue an operation permit, notifying the image data control means 105 and the panel control 101b that the operation is not permitted. Receiving the operation refusal notification, the panel control 101b indicates on the operator control panel 101a that the user is not registered (Step S 108).
  • the authorization code inputting means 102 also notifies the panel control 101b of the wrong authorization medium insertion and the panel control 101b displays on the operator control panel 101a that the authorization medium insertion is faulty.
  • the user chooses the operation to be executed on the operator control panel 101a (Step S 104).
  • the first operation to be executed by the user is filing in which the original image is read in by inage data inputting means 103 as optical reader image scanner and the read-in original image data is digitized and stored in the image storage means 108 (Step S 105).
  • the second operation is copying in which the image data read in by the image data inputting means 103 is printed on such media as paper and OHP sheet by the image outputting means 110 as, for example, electrophotographic printer (Step S 106).
  • the third operation is file outputting in which the image data filed in the image storage means 108 is ouputted from the image outputting means 110 (Step S 107).
  • this operation direction is held in the panel control 101b, and the panel control 101b notifies the image data control means 105 of the operation direction based on the operation permit of the function-limiting means 106, if the execute button on the operator control panel 101a is pressed. And the image data control means 105 acts according to the operation direction.
  • the authorization code inputting means 102 and the user ID inputting means are provided as shown, whereby the user authorization number can be inputted from the operator control panel 101a for identification of the user even if the authorization medium is not at hand. Besides, any person who is not registered with the user control means 104 is denied access to the apparatus.
  • the present embodiment is described in the case of the limit so set as to deny all the functions, but it is possible to confine the limit to the operations involving access to the image storage means 108 as, for example, filing and file outputting; in this case, too, the confidentiality of the image storage means 108 can be secured. Also, the limit can be placed not only on the functions with access to the image storage means 108 but also on any other function.
  • the operating means 101 also functions as user ID inputting means in which case the user authorization number is inputted on the operator control panel 101a.

  • the user control means 104 contacts the user control table 10 with the notified authorization code, and checks if the authorization medium 8 is already registered or not (Step S 702). If it is already registered, it is so indicated on the operator control panel 101a, with authorization medium 8 ejected (Step S 703) and with the mode returning to the initial state.
  • Step S 704 the user inputs the user authorization number on the operator control panel 101a (Step S 704).
  • the user control means 104 changes the user control table 10 for the user tallying with the inputted user authorization number from the formerly used authorization code to the one on the inserted authorization medium (Step S 705) as shown in Fig. 12.
  • the authorization medium 8 is ejected (Step S 706), completing the process of changing cards (Step S 707).
  • Step S 706 it is explained in the foregoing embodiment that if the inserted authorization medium is already registered, the mode will return to the initial state. It is also possible to finish the mode when the inserted authorization medium is already registered.
  • the user authorization number is inputted on the operator control panel 101a. It can be so arranged that a password is inputted in addition to the user authorization number. This can easily preclude the possibility of the image processing apparatus being used with some other's user authorization number. In case it is so arranged that a password is inputted in addition to the user authorization number, it has to be so configured that the user control table 10 has the password connected with the user authorization number.
  • a password tentatively inputted as by an apparatus service man can be changed to an easy one.
  • a process example of changing passwords is now explained briefly. First, the authorization medium is inserted into the authorization code inputting means 102 or the user authorization number and the password are inputted on the operator control panel 101a. Then, the password changing function is selected, and the password now in use is inputted on the operator control panel 101a. And a new password is inputted.
  • the user control means 104 contacts the user control table 10 and changes the password connected with the authorization code or the user authorization number. In this way, passwords can be changed with ease.
  • the authorization code inputting means 102 can be formed of any equipment using media that can give a distinctive authorization code to each card, i.e., the punched card reader and IC card reader, as well as the magnetic card reader.
  • the user ID inputting means is the operating means 101 provided with the operator control panel 101a.
  • the purpose is served just the same by such inputting means as keyboard, ten-key board and touch panel.
  • Remote operation is also possible by such serial communication means like LAN, IrDA and RS 232.
  • the image processing apparatuses according to the present invention if provided with the authorization code inputting means and the user ID inputting means, can identify the user by a user authorization number inputted from the user ID inputting means even if the authorization medium is not available at hand. And if the user can not be identified, the use of the image processing apparatus can be denied.
  • the reading out of the image data as unit is limited on the basis of the access right information on the image data to be read out and the group identification information on the user who wants to read out the data, the confidentiality of the filed image data can be raised.
